Question

Always forgetting your long passwords(密碼)? Worried about being hacked(被攻擊)?All these worries will soon become history. Scientists have found that upper-casing(大寫)your password can help you reduce the chance being hacked.
Usually passwords are six letters or more.However,50 percent of people choose a common word or simple key combination for their password. The most used passwords are 123456, abcdef and abc123. In fact, if your passwords are in lower-case(小寫),it will be easily hacked by a hacker. According to a study, it only takes a hacker ten minutes to hack a six-letter password which is in lower-case, but if you make the letter in upper-case, it can take up to ten hours. So if you want to make your account much safer, you should make your password upper-case. Of course, you can also add numbers or symbols to your password. Most of the time a hacker’s computer has to work for 18 days to break a password, but if you choose a nine-letter password that includes numbers and symbols, it can take a hacher’s  computer 44,530 years to break it.
